AIR-MOISTENING APPARATUS.

SIPECIIEIGATIOIIJT forming part of Letters Patent No. 497,034, dated May 9, 1893.

The invention consists in an air meistening apparatus constructed with a casing containing a fan-blower, a perforated drum filled with balls and means for conducting water upon said balls.

The invention further consists in the combination with said blower andthe perforated drum and the balls, of means for slowly rotating the drum so that all theballs will be wetted by the water conducted into the apparatus.

which will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure l is a vertical longitudinal sectional view of my improved air moistening apparatus. Figs. 2, 3 and 4t are vertical transverse sectional views, on the lines 2 2, 3 3, 4 4 respectively of Fig.

`1, and Fig. 5, is an elevation and sectionalr view of one of the balls used in the apparat-us.

Similar letters of reference indicate corref spending parts.

The cylindrical casing a is provided at its rear end with a cylindrical extension a', and the said casing a a is held between two ringshaped frames b b', which in turn are connected with each other by rods c c2 c3 c4 running parallel with the casing. shaped frames b b are provided at their upper ends with hangers OZ. by which they are fastened to the ceiling or other support. The ring-shaped frame b is provided with the radial arms f, which support the hub g. Said frame b is also provided with a funnel-shaped projection b2, and at the end of the same a ring h is arranged that has an approximately C-shaped cross-section, the open side of which ring h faces toward the center of the apparatus. On the end of said funnel-shaped ex- The ring i tension a cylinder z' having perforations t" is applied, and said cylinder lis surrounded by a jacket 7c, the diameter of which gradually increases toward the center of the apparatus, so that the distance between the cylinder i and jacket 7c is less at the outer end of said jacket z than it is at the inner end. The jacket 7c and cylinder t' are connected along the edges of said jacket and cylinder and at the bottom an outlet tube k is provided Afor conducting water out of the space between the jacket and cylinder.

In the rear ring-shaped frame b a similar frame Z is fastened, which is provided with radial arms Z carrying the hub Z2. To said ring-shaped frame b a plate m is secured, whichcloses the end of the casing of the apparatus. In suitable bearings in the hubs g and Z2 the shaft n is journaled, and on the l said shaft a` fan o is mounted within the perforated casing z', and on that end of the shaft adjacent to the end wall m a belt-pulley p is The invention also consists in the construction and combination of parts and details,

fixed. A tube r is mounted on the inwardlyprojecting ends ofthe hubs g and Z2 in such a manner that it can turn on the same, and on said tube two cylindrical end frames Zand s are fixed, which are provided with the arms t s respectively. Said end frames are connected by a cylindrical casing or drum uV of perforated metal or netting. A worm q is mounted on the shaftn a short distance from the pulley p and is engaged with the wormwheel u2 fixed on the shaft c suitably mounted in journals attached to the arms Z' of the frame t and carryingat the outer end a pinion c3 that engages a fixed cylindrical rack 'U4 attached to the inside of the casing a. As shown in Fig. l, the worm-wheel @2 passes through a longitudinal slot r of 'the tube r. Above the top of the casing a a tube ai is arranged parallel with the rotating perforated drum u. and above the same, which tube has both ends closed and is provided at the outer end with a funnel w3, through which water can be conducted into it. At the bottom said tube is `provided with perforations m2, and directly under said tube a slot .fr is formed in the casing a, and the tube fr is covered by an inverted trough-shaped cap-plate x4. The casing a is also provided at the bot- ICO tom with a longitudinal slot y and below the same a trough y is fixed to the casing a and an outlet pipe y2 is connected with the lowest point of said trough. The part a of the casing a. is provided on opposite sides with the openings a2 a3, at which the necks 102 w3 are connected with the casing, and if desired pipes can be attached to said necks for conducting air to the apparatus. The perforated drum a is provided with the perforated endwalls u a2, and the said end-wall u2 is provided with a gate-section a3 to permit of inserting balls z, preferably made of wood or balls are provided with the transverse bores z z2 z3. The rotative casing is entirely filled with such rotative balls.

The operation is as follows-The shaft 'n and the fan o are rotated at a speed of from eighteen hund-red to two thousand revolutions per minute. The fan-wheel draws the air through the apparatus, thus compelling the air to pass through the necks 102 w3 into the casing a and through the perforated drum. As thisdrum is filled with balls z the air must pass through said balls and spaces between them and thereby is moistened. Water continually drops from the pipe through the slot upon the balls, which absorb Water untilv they are saturated. As they are perforated they present a very large surface to the air passing through the apparatus, and as a result the air becomes fully moistened. So that all the balls are moistened and constantly change their positions, the drum u must be rotated slowly. This is accomplished by means of the worm-gear described, as the worm q rotates the worm-wheel o2 on the shaft fu. As the said shaft is mounted on one of the end-frames of the rotating drum and its pinion engages the fixed circular rack o4 it follows that the said drum must rotate slowly. The water that is not absorbed by the balls passes through the slot y into the trough y and then passes off through the outlet pipe y2. As the fan o rotates at a very high speed, particles of water are drawn along with the air, and to prevent them from passing into the room the ring h has been provided, against which the particles of water strike and flow down to the bottom of the same. But some particles of water even pass the ring h and are thrown by the fan o with the air against the perforated casing t and collect in the j acketed space between said cylinder 1l and the jacket 7c and iiow through the outlet-pipe 7c into the bottom of the casing a and from the same into the trough y. It is evident that the coarser impurities are held back by the screens or perforated plates of the apparatus and also adhere to the balls and are washed from the same by the streams of water. Chemicals for disinfecting the air can be added to the water that is used for moistening the balls, so as to disinfect the air. If hot water is used in the apparatus the air is heated at the same time, and if cold Water is used in summer the air is cooled.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In an air-moistening apparatus, the com- I bination with a casing, of a rotative fan-blower, a perforated drum in the casing, means for `rotating said drum, perforated balls in said drum and means for conducting water upon said balls, substantially as set forth. other material adapted to absorb water, which 4 bination, witha casing havinga funnel shaped 2.
